Huawei Updated H19-301_V3.0 Exam Questions and Answers by aren

Huawei’sFree Mobilitysolution providesconsistent network accessusingUser-Based Policy Control.

(B) True – User-Based Policy Control:

Ensures thatuser policies(VLAN, QoS, security) remainconsistentacross the network.

Users canmove freelyacross different subnets while maintainingthe same network access privileges.

Other options:

(A) IP Address-Based Control (False): Users' IP addresses may change, disrupting policy continuity.

(C) MAC Address-Based Control (False): MAC addresses aredevice-specific, limiting user mobility.

(D) Terminal-Based Control (False): Controls access perdevice, not per user.

In adata center network, three primary types of resources are connected:

Storage:Includes storage arrays and systems that provide data persistence and retrieval capabilities.

High-performance computing (HPC):Supports compute-intensive workloads like scientific simulations and AI training.

General-purpose computing:Handles everyday workloads such as web hosting, application servers, and virtual machines.

These resources are interconnected through the data center network, enabling seamless communication and resource sharing. Each type serves a distinct purpose, catering to different application requirements.

Common Attack Methods in Enterprise Networks:

Enterprise networks are vulnerable to various cyberattacks, targeting both infrastructure and applications.

Explanation of Each Attack Method:

Command line injection:Exploits vulnerabilities in command-line interfaces to execute unauthorized commands.

Brute-force attacks:Attempts to guess passwords or encryption keys through exhaustive trial-and-error methods.

Cross-site attacks:Includes cross-site scripting (XSS) and cross-site request forgery (CSRF), targeting web applications.

Remote code execution:Exploits vulnerabilities to execute arbitrary code on a target system, often leading to full system compromise.

Conclusion:All four options represent common attack methods faced by enterprise networks.

Huawei Cybersecurity White Paper.

A WLAN (Wireless Local Area Network) is specifically defined as a network that uses radio frequency (RF) technologies , primarily Wi-Fi, to provide wireless connectivity. While technologies like infrared, Bluetooth, and ZigBee are wireless communication methods, they are not part of the WLAN definition.

Wi-Fi : Operates in the 2.4 GHz and 5 GHz frequency bands and is the primary technology used in WLANs.

Infrared : Uses light waves for short-range communication and is not part of WLAN standards.

Bluetooth : Designed for short-range personal area networks (PANs), not LANs.

ZigBee : Used for low-power, low-data-rate IoT applications, not WLANs.

Thus, the statement is FALSE , as WLANs are exclusively based on RF technologies like Wi-Fi.
